IMPROVEMENT IN METALLIC SHINGLES.

Specification forming part of Letters Patent No. 207,989, datedSeptember 10, 1878; application filed May 16, 1878.

To all whom it may concern:

Be it known that I, HENRY W. SHEPARD, of Brooklyn, New York,'haveinvented certain Improvements in Metallic Roofing-Shingles, of which thefollowing is a specification:

My improvements relate to the sheet-metal diamond-pointed shingles whichhave heretofore been made with a central hollow rib, and

' with raised sides, as shown in Letters Patent of theUnited States No.194,766, granted to O. Oomstock, September 4, 187 7 and my inventionconsists, first, in transversely slitting the obtuse corners of suchshingles, and thus providing them with tongues for lapping over andholding down the points of the shingles in the nextimmediately-following course; secondly, in forming hollow ribs along theinclined edges of each shingle, for the purpose of assisting instiffening and holding down its pointed end; and, thirdly, in formingslightly smaller ribs in a reverse direction from each of the obtusecorners of the shingle diagonally upward, the object of the smaller ribsthus formed being to enter the grooves on the under sides of the ribsalong the inclined edges of the overlapping shingles, and thus, whileadding stiffness to the shingle, serving to prevent rain from drivin gupward between the courses.

The accompanying drawings are as follows: Figure 1 is a top view of aportion of four consecutive courses of shingles containing myimprovements. Fig. 2 is a section through the line w a: on Fig. 1. Fig.3 is a section through the line 3 3 on Fig. 1.

For convenience of illustration, the drawings show but one shingle, A,in the upper course, two shingles, A A in the next course, three, -A AA, in the next course, and the upper portions of four, A A A A in thenext course. Each shingle is provided with a central longitudinal hollowrib, B, and has its parallel edges b I) turned upward, so that theadjoining edges of two shingles enter the longitudinal groove on theunder side of the ribB in the overlapping shingle. It will f be seenthat near the obtuse corners of each shingle there is a transverse slit,0, and that the metal below the slit is sprung upward to allow the pointD of the overlapping shingle to pass under it. The metal thus sprungupward forms the pointed tongue 0, which laps over the lower corners ofthe pointed end of the overlapping shingle on either side of the lowerend of the central rib B.

Along the inclined edges of each shingle the hollow ribs E E are formed.The ribs E E terminate at their lower ends at a short distance above thepointed end of the shingle, and at their upper ends are turned inward,forming the curved hollow ribs 6 c. The inwardly-curved ribs 6 e havethe two objects of pearance.

addition to these objects, are further intended to receive the ribs F Fin the two underlying shingles, which the pointed end of each shinglerests upon. The ribs F F, it will be seen, extend inward and upward fromthe obtuse corners of the shingle, and are fitted by their location andby their dimensions to enter the grooves on the under sides of thehollow ribs E E. The ribs F in one course of shingles thus engaged bythe ribs E in the next following course of shingles tend to prevent rainfrom being driven .upward between the courses.

I claim as my invention- 1. A metallic roofing-shingle, substantiallysuch as described, provided with the tongues 0 c, substantially as andfor the pinposes set forth.

2. A metallic shingle having the hollow ribs E along the inclined edgesof the lower end of the shingle, and the curved hollow ribs 0 e,substantially as shown and described.

3. Metallic shingles, substantially such as described, provided with theribs E E along their inclined edges, and the ribs F extending inward andupward from a point near the obtuse corners of the shingles,substantially as and for the purposes set forth.
